First, just ask -- nicely -- for the person to take the photos down or crop them so your kid isn't in them.
If you're OK with a photo but only want certain people to see it, ask the poster to enable settings that limit who can see the photo to a small circle.
If your kid is on Facebook and is tagged in a photo, everyone in her friend network will see it. She can untag the photo (it will still appear, but it won't be linked). We recommend using the privacy setting that lets you approve a tag before it goes live. — Common Sense Media The opinions expressed are solely those of the author and do not necessarily reflect the views of Comcast.
